Sticks 2l may then. be inserted into the ice creamcontents of the receptacle, through Athe aligned slots I9 and 20, thusholding the naps in closed position.

In producing pops adapted to be contained or packaged in theabove-described container, a simplinedmethod of manufacture may bereadily followed. `Assuming that vthe pops are to be composed of anicecream center covered bya choco-v lateA or lsimilar edible., outercoating; it is iirst desirable that the interiorof .the channel-shapedreceptacle or` partitioned paper .trough be lined` substitute for thisprocedure,'the'excess chocolatev might be Withdrawn from the interior of`the paper receptacle-bysuction orrotherl means, =leav ingthe coatingadherent tothe insidehwall surfaces ofthe receptacle as above explained.

Several other methods -of coating the interior Wallsof the -paperreceptacle' may be followed,Y the result-of each method being to leaveAan ad@ herent edible-'coating on the linterior'walls, suchenclosed'commodities; mestlof the expensive maw the closure naps 8 and 9are'folded'inwardly-or toward one another and into overlapping position,

The filled and closed receptacle, with the sticks 2l in place, andappearing as indicated in Fig. 6, is now carried on a suitable conveyor,or by hand, to a freezing chamber where the contents of the receptacleare frozen to required hardness. The complete product is then alengthy,completely enclosed block made up @ofja vpliirality 'of pops. Each popr`is separatedfrom its ycompanions by severance along each of the tear orseparation lines I8, and separation of the parts of the Arwrapliler,along..,the,se lines will also result in separation of the two plies ofpartition II at which the tear line I8 is located. The resultant wrappedor enclosed pop is seen in Fig. 5 wherein it will be Qberyedthat thesame is fully enclosed by the end walls composed of one ply each of twopartitions-and by an encircling narrow strip section 22 removed from thewrapper I. The pop thus enclosed isV protected, maintained in sanitarycondition and cannot Vbe exposedwithout Vtearing. at least oneof the aps8 orx9outwardly from the slots I9 and 20fformed insaid flaps. Suchtearing. or destruction of :the flaps constitutes a tell-tale at onceindicating to the Vendor that the wrapper has been opened and he thus isobli. gated to refuse to take back orvexchange arpop, the wrapper ofwhich has been .tampered with. When the outer flapis pulled free fromthe stick, by destruction of-the slot I9, theentire wrapper may then bereadily peeled offsince the tongue. and-slit connection between the.vwrapper vsection 22 andtheplies of the vpartitions is such asV topermitreadyv separation Yof the encircling part 22 Vof. the wrapper fromthese partition elements.4 Thepeeling of the. wrapper in thelniannervde,

and adhering to theiice cream, will form the outer coatingltherefor. z

The-arrangement. of the. several parts Yof the wrapperand the manner ofco-operation between thesame is such thatthe folding-.of the wrapperbody I-,'fthe insertion? of L`the partitions, the
